I've got a webpage that is checking to make sure various are entered and that they match when a user clicks the button. I've only got labels that display a message and I'm getting the error below.

"Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application"

I don't understand, I've got no dialog boxes anywhere in my site.

Can someone provide me some ideas as to where I need to look to isolate and fix this problem?
